Phys.org / Scientists unlock evolution of gigantism in Scottish island wrens
A new study of British wrens has provided new insights into the inner workings of "island syndromes," according to research led by the University of Birmingham. The paper, published in the Evolutionary Journal of the Linnean ...
Phys.org / Rare observations reveal an X9 solar flare before it erupts
Solar flares are powerful bursts of radiation from the sun's surface, which can wreak havoc on Earth's power grids, damage orbiting satellites, and pose serious radiation risks to astronauts. Yet despite decades of study, ...
Phys.org / Forgotten museum fossil helps rewrite part of animal evolution
New research published in BMC Biology helps to fill in questions about the so-called "Furongian gap" from about 497 million to 485 million years ago, when paleontologists previously thought there were far fewer fossils than ...
Phys.org / Outdoor lights may keep mosquitoes biting and breeding deeper into autumn
In some parts of the world, autumn brings welcome relief from mosquitoes, such as the Northern house mosquito (Culex pipiens). As the days grow shorter, the waning light is a signal for them to enter a winter state of dormancy ...
Phys.org / A rare blue micromoon rises this weekend
Get set for a rare blue micromoon this weekend—a blue moon that's also the most distant and smallest-looking full moon of the year.
Phys.org / Chang'e-5 regolith studies reveal nanoscale space-weathering processes
On the moon, the lack of atmosphere and accompanying features such as biological activity, oxygen-rich air, flowing water and rain, wind, and most erosion allows the lunar regolith to preserve a long-term record of surface ...
Medical Xpress / Psychiatric 'gold standard' falters as repeat interviews yield different diagnoses
Diagnostic interviews are widely used by mental health professionals to identify conditions such as anxiety, bipolar disorder and depression in adults, but new research led by McMaster University shows that the long considered ...
Medical Xpress / Young adults are more perfectionistic than ever before, study finds
College students feel more pressure to be perfect than they did a generation ago, finds research published in Psychological Bulletin. That increase in perfectionism may be tied to social and economic factors such as rising ...
Medical Xpress / Depression may not only be a consequence, but also a cause of rheumatoid arthritis
According to researchers at Semmelweis University, not only inflammation, but also sleep disorders, depression, obesity, and smoking may sustain persistent rheumatic symptoms. In their publications in the journals Nature ...
Phys.org / Think it's hot now? The next five years will smash records, UN says
In the next five years, the Earth is overwhelmingly likely to surge again and again past the international climate threshold set as safe and shatter its hottest-year record along the way, according to new United Nations climate ...
Phys.org / Newly discovered 'thunder' of Atlantic sturgeons inspires awe
When a team of researchers recorded a low thundering underneath the surface of the Hudson River, they thought they were hearing the muffled rumble of trains. A closer look and listen led to a much more interesting discovery: ...
Phys.org / Hyena clan rank metrics need to be trait specific to fully explain hierarchies, scientists argue
Spotted hyenas live in hierarchically organized groups (clans). An individual's dominance over another determines priority access to resources such as food or mating partners, and thus reproductive success. However, the rank ...
